The Gateway routes requests through the Provider Registry. Account Sync refreshes credentials, quota, and models. Each Provider keeps independent account state and uses an isolated egress scope; usage, audits, and client billing are finalized after the request.

Each Provider keeps its own credentials, quota, health, cooldown, concurrency, and model capabilities. Account retries stay within one route; when one public model ID intentionally aggregates multiple routes, the gateway may select another schedulable route without mixing Provider state.
Quick start
Official images support linux/amd64 and linux/arm64.
git clone https://github.com/chenyme/grok2api.git
cd grok2api
cp config.example.yaml config.yaml
Generate secrets and place them in config.yaml:
openssl rand -hex 32
openssl rand -base64 32
secrets:
jwtSecret: "replace-with-the-generated-hex-value"
credentialEncryptionKey: "replace-with-the-generated-base64-key"
bootstrapAdmin:
username: "admin"
password: "replace-with-a-strong-password"
Start the service:
docker compose pull
docker compose up -d
docker compose logs -f grok2api
Open http://127.0.0.1:8000. The image already includes the frontend; SQLite data and local media are stored in the Compose volume.
Run from source
cp config.example.yaml config.yaml
make run
For frontend development:
cd frontend
pnpm install
pnpm dev
Set up the gateway
- Sign in with the bootstrap administrator.
- Connect a Build, Web, or Console account.
- Wait for its quota and model capabilities to sync.
- Review the public routes under Model Routes.
- Create a client key under Client Keys.
- Call a
/v1/* endpoint with that key.
After first sign-in, change the administrator password and remove bootstrapAdmin from the configuration. Never rotate credentialEncryptionKey after credentials have been stored.

Imports accept UTF-8 BOM. Bulk quota sync, Build credential renewal, Web→Build/Console conversion, account tools, and cleanup report live progress.
Build refresh tokens may rotate when renewed. Do not actively share one Build credential between grok2api, the official CLI, another gateway, or another independent client: one client can consume a token that another client still holds. Authorize each active client separately, or transfer the credential only after the previous client has stopped using it.
Web account tools can accept the terms, set a random birthday corresponding to an age of 20–40, and enable NSFW. Completed steps are recorded and skipped on later runs.
Automatic deletion of old reauthRequired accounts is available but disabled by default. Active inference leases and video jobs are protected.
[!TIP]
To migrate from the Python version, export Grok Web SSO tokens as TXT and import them under Grok Web. Old pool metadata and databases are not compatible.
Models and routing
Build models are discovered from each account's actual capabilities. Web and Console use built-in catalogs. The Model Routes page shows Provider-qualified routes, endpoint capabilities, and supporting-account counts; clients should treat the currently serviceable results from GET /v1/models as authoritative.
Grok Build
Build does not use one global static model list. Account synchronization reads the upstream /models endpoint, and different accounts, subscription tiers, or staged rollouts may expose different models. Routing retains these per-account capabilities instead of replacing the global catalog with one account's response.

Conversation requests are translated to the Build Responses protocol while preserving the tool, reasoning, multi-turn, and prompt-cache compatibility required by Codex and Claude Code. Build currently exposes no image generation or image editing routes.
Grok Web
Web uses a built-in catalog filtered by account tier; higher tiers inherit lower-tier models.

Web Imagine generation maps aspect_ratio and n to the browser protocol. size remains an OpenAI-compatible aspect-ratio alias, while generation-only resolution and quality are ignored on Web routes because the upstream product is selected by the model name rather than by those Console-oriented controls.
Grok Console
Console uses the catalog built into the current release. Conversation forwarding is stateless, while image, video, and voice use the standard xAI resource APIs.
